projectZero ESP32-C5

Flash projectZero straight from your browser

WebSerial flasher powered by esptool-js. Use Connect + Flash for firmware, or run Serial Monitor as a separate mode to read/write UART data in browser.

Control

Ready to connect.
Erase does a full flash erase (esptool erase-flash) before writing the images. Only enable it when you have OTA partitions / old firmware and you see bootloops or slot errors. Note: it wipes anything stored in flash (including NVS settings like Wi-Fi creds/config).

Serial monitor

Independent UART terminal mode. You can read and write serial data directly from browser.

Monitor disconnected.

Release info

Loading manifest

  • ROM mode: Hold BOOT on the LAB C5, plug the board in, then release.
  • Close serial hogs: quit qFlipper/monitors or anything holding the COM port.
  • Stuck- Unplug, re-run Connect, plug again with BOOT held, then Flash.
  • Reset: after flashing, press RESET on the board if it does not auto-reboot.

    • What happens

    Using esptool-js directly: enter stub, set baud, then flash each image at the offsets from manifest.json. Progress and MD5 checks mirror the Python esptool flow.

    Need offline-

    Grab the same assets from Releases and run flash_board.py in ESP32C5/binaries-esp32c5 if your browser blocks Web Serial.
